Miniature rose plant named Bismar

ABSTRACT

A new and distinct variety of miniature rose plant characterized by (1) bright coral pink buds and blooms with pale pink satiny reverse and (2) a vigorous, compact plant with abundant glossy green foliage.

The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was originated by my crossing as seed parent the floribunda rose known as "Little Darling", (U.S. Plant Pat. No. 2,909 expired) and a miniature rose "unknown seedling" as pollen parent.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are: (1) high-centered blooms of bright coral pink with pale pink satiny reverse coloring, (2) an abundance of blooms with flowers borne singly, and often several to a stem in a loose cluster, (3) a pleasant fruity fragrance, (4) a well proportioned plant which is vigorous and shows off its blooms well against its green glossy foliage, and (5) a plant which grows well both in the greenhouse and outdoors, is good for growing in pots, and provides excellent garden decoration as well as cut flowers.

The present variety of miniature rose was originated by me in Marion County, Ind. Carefully controlled conditions and asexual reproduction by cuttings of the new variety as performed by me in Marion County, Ind. show that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it is reasonable possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (RHSCC) except where common dictionary terms of color definition are employed.

I claim:
 1. A new and distinct variety of rose plant of the miniature rose class, substantially as herein shown and described, characterized particularly by high-centered blooms of bright coral pink with pale pink satiny reverse coloring, with firm, thick petals, borne freely on an upright, bushy plant with glossy green new foliage and semi-glossy darker green old foliage, said plant being easy to propagate from cuttings, and said blooms being long-lasting both on the plant and as cut flowers.
